HBS unit 3 study guide

removes metabolic waste from the blood which came from cells – urea, toxins, drugs (excretory system function)
maintain blood volume and concentration
balances various products and removes excess from the blood in the form of urine (excretory system function)
filter blood to make urine, maintain homeostasis by controlling the chemical composition of the blood
tubes that carry urine from kidney to urinary bladder
urinary bladder
stores urine until it is expelled
tube through which urine is expelled from body
renal artery
carries blood to the kidney
renal vein
carries blood away from the kidneys
inferior vena cava
major vein that the renal vein flows into. carries blood back to heart
major artery that delivers blood from the heat to the renal artery
renal cortex
outer region of the kidney
renal medulla
consist of cone shaped pyramids that lie on the inner part of the renal cortex
renal pelvis
area where urine collects and is transported to the bladder through the tube called the ureter
filter out urea and other solutes ( salt, sugar)
blood plasma
………….. filtered into nephron
fluids from blood collected. includes water and solutes
selectively reabsorb needed substances back to blood
pump out unwanted substances to urine
bowmans capsule
site of filtration, formation of filtrate
proximal tubule, loop of henle,
distal tubule
secretion, reabsorption
collecting duct
carries urine to renal pelvis, reabsorption, secretion
respiratory system
gas exchanges between the blood and external environment
internal respiration
an exchange of gases between the cells of the body and the blood way of the fluid bathing the cells
external respiration
gas exchange between pulmonary blood and alveloi. oxygen is loaded into blood. co2 is unloaded from blood
tidal volume
the volume of air breathed in and without conscious effort (subconscious, normal breathing)
reserve volume
additional volume of air that can be forcibly exhaled after normal exhalation of forcibly inhaled
involuntary breathing
digestive system
mouth, pharnx, esophagus, stomach, small intestine, large intestine
enzyme producing gland located below the stomach and above intestines, excretes enzymes to break down proteins, lipids, carbs, and nucleic acids in foods
small intestine
absorb nutrients, glands in intestine walls help break down sugars and starches
large intestines
removes water and salts (electrolytes) from undigested material and to form solid waste that can be excreted
chewing, process by which food is crushed and grounded by teeth
makes food in stomach break down in size giving larger Surface area
continues breakdowns of starches(sugars)
breaks down proteins into large peptides
simple/ complex..sugars/starches
burning of fat this is caused when body runs out of insulin
increases water reabsorption in distal convoluted tubule and collecting duct. decreases the amount of water lost in urine (decreases urine volume) which increases blood volumes
oxygen combined with RBC
% of filtration eventually reabsorbed into blood stream
visceral membrane, pulmonary pluera
surface of lungs
parietal pluera membrane
lines walls of thoracic cavity
1.0010 dilute
specific gravity
plueral fluid
fills in area btwn the two layers
